here my overall thoughts about this ctf. On difficulty alone, I'd weight it around 40-45, as they have some decently hard revs and pwns (though I heard the crypto was kinda weak)... with that being said, I have a few nitpicks, and if there were to be a future iteration of this ctf (just to reiterate, I think challenges were okay difficulty and weren't guessy/bad, my issue really I guess is with the overall execution rather than the concepts themselves):
- infra was unstable at the beginning, (ctfd tends to be super laggy if you don't load balance it correctly when everyone starts pinging the server at the beginning of a ctf)
- with ultrushawasm rev, the concept was interesting, tho the overall execution was poor. our team didn't personally solve it, so I can't be entirely sure of it, but imo searching though tons of rust library code compiled to wasm for some backdoor really wasn't a super great use of time to be spending. It honestly also seems like a low-effort type challenge (as I suspect the author probably wrote maybe a few lines of rust and maybe added some magic backdoor, and then called it a rev challenge), and the compiler does most of the work for you.
- pwnbox was interesting, but might've benefited from some message saying that vdso isn't a standard from one of the more common ubuntu distros, if not provided outright, especially since it seems pretty critical for this challenge. I can see part of the intended solution was to leak vdso, but our team ended up spending quite a bit of time before then trying to test every single vdso in common ubuntu 18.04/20.04/etc...
- generally I don't like challenges that take large random oss projects and make a few patches/changes and call that a challenge, unless that is something well-known/popular/ubiqitous (i.e. linux kernel/ browsers/etc...) since it also requires the player to have a prequisite of understanding how the project(s) mesh together, before even starting to do some pwning (i.e. flagtrust, sqg). flagtrust is probably the bigger offender here with having a couple of libraries in golang compiled to wasm (one of them I think has some specs for some blockchain-like vm), that is run by some lesser known wasm interpreter of some sort.
- this ctf is also only 24hrs long, having plenty of hard and "long"-going challenges, and therefore, likely that there are many challenges unsolved. I guess if it were a 48hr, it would probably give most teams at least some time to be able to solve some of the harder challenges, but that would also require maybe adding a few more challenges in the various categories.
Anyways the challenges here are still nice, considering the ton of other ctfs out there with a ton of easy/shoddy/guessy challenges, where many teams end up competing for how quickly they can solve every single guessy challenge. I just think some of the challenges here could have better execution, but this is the first ctf by LINE so I guess a good first one.
